For PC, Quake was a good example for DOS, which later got ported to Windows. Most of the games that used Redbook audio were around the DOS-era as at that time, sound cards were not readily able to handle 44.1kHz samples and that hard drives (notably when they were still using FAT16 file system) were too small to have them stored locally while still keeping a reasonable amount of free space (a typical CD can hold up to 700MB/80mins of Redbook audio, compared with FAT16 file system which is capped at 2GiB), not to mention the CPUs were also not strong enough to reasonably perform decoding and resampling while keeping other stuffs responsive.

Redbook CD audio covered quite a few other platforms at that time as well, not only PC and not only DOS/Windows. A notable example is the PC-Engine (Turbografx-16) CD. I think some other platforms (like PlayStation and Sega Saturn) might have some titles that used Redbook or similar CD audio formats as well.
